A player can equip up to 3 Evolved Bacteria at one time, but there are no limitations as to how many Evolved Bacteria can be owned.
The Evolved Bacteria that are equipped provide bonuses to production, increased critical strike chance and multiplier, reduced research time, and other positive effects.
When entering a Black Hole, there is a default 90% possibility that an Evolved Bacteria will die. Before entering, the player can secure two Bacteria that will definitely survive.
When the player destroys the fifth planet after the first Black Hole, Bacteria Irradiation is unlocked. It is accessible from the Research Lab and can increase the black hole survivability of an Evolved Bacteria.
There are 5 different Evolved Bacteria rarities:
Higher rarity Bacteria are more difficult to obtain and have more powerful stats.
After an Evolved Bacteria has been obtained, it cannot be increased in rarity.
Bacteria droprates differ depending on their rarity:
Each equipped bacteria can boost 1-5 stats.
Higher rarity Bacteria are always stronger, but same level and rarity Bacteria aren't always equally powerful.
The number of stats that a Bacteria can have depends on its rarity:
|Rarity||Number of stats|
Possible stats include:
|BPS||Increase BPS by X%|
|BPC||Increase BPC by X%|
|More Gene Strands||Increase the amount of Gene Strands earned when attacking a planet by X%|
|Idle BPS||Increase idle BPS by X%|
|Reduced colonies price||Reduce the price of colonies by X%|
|Reduced Gene Strand upgrades price||Reduce the price of Gene Strand upgrades by X%|
|Critical chance||Increases the chance that a tap will result in a Critical Bacteria by X%|
|Critical effect||Increases the effect of the Critical Bacteria by X%|
|Infectivity||Reduces the number of Bacteria needed to destroy a planet by increasing the Bacteria spreading speed by X%|
|Reduced research time||Reduces the duration of all research by X%|
Mutation requires two Bacteria of equal level and gives one Bacteria of a higher level as a reward. The rarity of the mutated Bacteria is the same as the rarity of the used Bacteria. If they are of different rarities, the mutated Bacteria will have a random rarity in the same range, so it is not possible to obtain a higher rarity Bacteria through mutation.
The default mutation cap is Level 3, which can be raised to Level 4 with the Ultimate Life Form tech at the Dark Matter Institute.

Black Hole Survival Probability
Each Evolved Bacteria has a default 10% Black Hole survival probability. It can be raised through Bacteria Irradiation at the Research Lab. It is unlocked when the fifth planet after the first Black Hole is destroyed.
Viewing the survival probability of a Bacteria is possible after the first Black Hole. To do this, open the list of Evolved Bacteria and tap on a Bacteria of your choice. The survivability should be visible just below the Bacteria's stats.
The default survival probability cap is 30%. It can be raised to 50% by researching Hazard Elimination at the Dark Matter Institute.
Evolved Bacteria can be deleted in the list of Evolved Bacteria. Deleting an Evolved Bacteria doesn't give the player any reward.
The names of Evolved Bacteria are based on real bacteria species, but their visual representations are not accurate to their real-life counterparts.
The name of an Evolved Bacteria doesn't influence its rarity and stats.
Possible Evolved Bacteria names include:
- Bacillus cereus
- E. coli
- Vibrio choler
